Method and System for Assessing Relevant Properties of Work Contexts for Use by Information Services

1. A method for obtaining representative text items from a plurality of text items in computer tasks, the method comprising: receiving first information indicative of a first computer task, the first information including a first plurality of text items; determining a first user profile associated with the first computer task; for each of the first plurality of text items, assigning a first weight with a first magnitude, the first magnitude being determined based on the first user profile; ranking the first plurality of text items based on the first weight assigned to each of the first plurality of text items to produce a first plurality of ranked text items; generating and storing first representative text items based on the first plurality of ranked text items; wherein the first computer task is a task other than entering search terms for the purpose of retrieving information; receiving second information indicative of a second computer task, the second computer task being different than the first computer task, the second information including a second plurality of text items, wherein the second plurality of text items is different than the first plurality of text items; determining a second user profile associated with the second computer task; for each of the second plurality of text items, assigning a second weight with a second magnitude, the second magnitude being different than the first magnitude; ranking the second plurality of text items based on the second weight assigned to each of the second plurality of text items to produce a second plurality of ranked text items; and generating and storing second representative text items based on the second plurality of ranked text items; wherein the second computer task is a task other than entering search terms for the purpose of retrieving information.

2. The method of claim 1 , wherein the first magnitude is determined based on a stylistic attribute associated with the first plurality of text items.

3. The method of claim 2 , wherein the stylistic attribute includes at least one of font style, line height, font size, and associated hyperlink.

4. The method of claim 2 , wherein the stylistic attribute includes at least one of a list element, a heading, a table heading, a table cell, a navigation bar, a menu, a header, and a footer.

6. The method of claim 1 , wherein the first computer task includes shopping.

7. The method of claim 6 , wherein the first representative text items includes a product name.

8. The method of claim 7 , further comprising retrieving and displaying a coupon related to the product name.

9. The method of claim 8 , further comprising retrieving and displaying a dealer related to the product name.

10. The method of claim 1 , wherein the weight assigned to at least one of the first plurality of text items is increased in response to the text item being located in a specific region of the first computer task.

11. The method of claim 10 , wherein the specific region is a region of the first computer task that is selected by the user.

12. The method of claim 1 , further comprising forming a plurality of search terms based on the result of ranking the first plurality of text items.

13. The method of claim 1 , further including the step of determining properties of the first task; wherein the assigned first weight is tunable based on the properties of the first task.

14. The method of claim 13 , wherein the properties of the first task include at least one of application software being employed to perform the first task, a type or genre of the first task, attributes related to a user, properties of an information source on which a search will be conducted, and a state of the first task.

15. The method of claim 1 , wherein assigning the first weight is based on a user's role in an organization.

16. The method of claim 1 , wherein assigning the first weight is based on a location of a document associated with the first computer task, the location being determined by at least one of an associated URL, a file name, a directory name, and a string indicative of a file location.

17. The method of clam 1 , comprising: obtaining search results from at least one information source based on the first representative text items; processing and organizing the search results based on the user profile; and storing the search results.

18. The method of claim 1 , comprising: selecting at least one information source based on the user profile; obtaining search results from selected information sources based on the first representative text items; and storing the search results.

19. A data processing system for obtaining representative text items from a plurality of text items in computer tasks, the system comprising: a data processor for processing data; a data storage device for storing instructions; and a data transmission path coupled to the data processor and the data storage device, wherein the instructions, when executed by the data processor, controls the data processing system to perform the machine-implemented steps of: receiving first information indicative of a first computer task, the first information including a first plurality of text items; determining a first user profile associated with the first computer task; for each of the first plurality of text items, assigning a first weight with a first magnitude, the first magnitude being determined based on the first user profile; ranking the first plurality of text items based on the first weight assigned to each of the first plurality of text items to produce a first plurality of ranked text items; generating and storing first representative text items based on the first plurality of ranked text items; wherein the first computer task is a task other than entering search terms for the purpose of retrieving information; receiving second information indicative of a second computer task, the second computer task being different than the first computer task, the second information including a second plurality of text items, wherein the second plurality of text items is different than the first plurality of text items; determining a second user profile associated with the second computer task; for each of the second plurality of text items, assigning a second weight with a second magnitude, the second magnitude being different that the first magnitude; ranking the second plurality of text items based on the second weight assigned to each of the second plurality of text items to produce a second plurality of ranked text items; and generating and storing second representative text items based on the second plurality of ranked text items; wherein the second computer task is a task other than entering search terms for the purpose of retrieving information.

20. The system of claim 19 , wherein the first magnitude is determined based on a stylistic attribute associated with the first plurality of text items.

21. The system of claim 20 , wherein the first stylistic attribute includes at least one of font style, line height, font size and associated hyperlink.

22. The system of claim 19 , further comprising forming a pl of search terms based on the result of ranking the first plurality of text items.

23. The system of claim 19 , wherein the first computer task includes shopping.

24. The system of claim 23 , wherein the first representative text items includes a product name.

25. The system of claim 24 , further comprising retrieving and displaying a coupon related to the product name.

26. The system of claim 25 , further comprising retrieving and displaying a dealer related to the product name.
